Developers describe J2ObjC as "Java to iOS Objective-C translation tool and runtime used by Google Inbox to share 70% of its code across Android, iOS, and Web". J2ObjC is an open-source command-line tool from Google that translates Java code to Objective-C for the iOS (iPhone/iPad) platform. This tool enables Java code to be part of an iOS application's build, as no editing of the generated files is necessary. The goal is to write an app's non-UI code (such as data access, or application logic) in Java, which is then shared by web apps (using GWT), Android apps, and iOS apps. On the other hand, Web Starter Kit is detailed as "Boilerplate & Tooling for Multi-Device Development". Web Starter Kit is a starting point for multi-screen web development. It encompasses opinionated recommendations on boilerplate and tooling for building an experience that works great across multiple devices. We help you stay productive and aligned with the best practices outlined in Google's Web Fundamentals.

"Backed by Google" is the top reason why over 3 developers like J2ObjC, while over 2 developers mention "Easy to use" as the leading cause for choosing Web Starter Kit.
